Realistic PRO-43 - Connecting an Earphone.8

CONNECTING AN EARPHONE
For private listening, plug an earphone into the O jack on
top of your scanner. This automatically disconnects the
speaker. We recommend Radio Shack’s earphone Cat. No.
33-175. In a noisy environment, mono headphones (Cat.
No. 20-210) make listening easier.
Hearing Comfort and Your Health
To protect your hearing, follow these guidelines when you
use an earphone:
• Do not listen at extremely high volume levels, especially
when you use an earphone or headphones. Extended
high-volume listening can lead to permanent hearing
loss.
• Set the volume to the lowest setting before you begin lis¬
tening. After you begin listening, adjust the volume to a
comfortable level.
• Once you set the volume, do not increase it. Over time,
your ears adapt to the volume level, so a volume level
that does not cause discomfort might still damage your
hearing.
